Nixie tubes are beautiful pieces of display hardware that are no longer in production, and are becoming harder and harder to find. They also generally require relatively high DC voltages to operate, making them difficult and potentially dangerous. Connor Nishijima, however, has come up with an alternative called the Lixie. Using a series of etched acrylic […]
With Timothy Giles’ rotating digital picture frame, you’ll never have to endure black bars around your vertical images again! Rather than accept the poor presentation of vertical images that normal displays offer, Giles instead made his own out of a discarded 27-inch LCD TV. A Raspberry Pi displays the images sideways, then uses an Arduino […]
With Alain Mauer’s Arduino glasses and a Bluetooth® multimeter, electrical data is always in view! If you’re in a job where you have to take readings inside a live electrical panel, one thing that’s inconvenient, and even dangerous at times, is having to look away from your hands to read your multimeter. With hopes of […]
Spectroscopy is an incredible tool for chemical analysis–and now you can make your own Bluetooth-enabled device with an Arduino Pro Mini. If you took advanced chemistry classes, you may have had the opportunity to work with a spectrometer. It probably seemed like a magical gadget, identifying the chemicals in a substance through its light characteristics unlike the […]
